She did it!
Jennifer Aniston is never one to shy away from a challenge…
Aniston, who was dressed casually and sporting a pair of glasses, was every bit the good spirit and joked that the water was poured slowly.
The brunette beauty nominated a few of her famous friends in the clip: Courteney Cox and Chelsea Handler. Now only time will tell (24 hours to be exact) if these two follow through with the A-lister's nomination!
Earlier in the weekend, Theroux completed the challenge on his own in a hilarious video.
He accepted Jason Bateman's challenge and got completely soaked (we mean really soaked) when his pal tossed a huge bucket on him.
The Leftovers actor immediately called out his bride-to-be and explained why: "because she's not here with me to see this!"
Reese Witherspoon, Tom Hanks, Harry Styles, Olivia Wilde, Gwyneth Paltrow, Chris Martin, Benedict Cumberbatch, Tom Hiddleston, Taylor Swift and many, many more celebrities have also joined in on the challenge which raises both awareness and money towards the disease.
